No. 16/288,023, filed on Feb. 27, 2019, which is a continuation of International Application No. PCT/CN2017/092213, filed on Jul. 7, 2017. The contents of the above identified applications are incorporated herein by reference in their entireties.

TECHNICAL FIELD

The present disclosure relates to the field of communication technologies and, in particular, to a data indicating method and related products.

BACKGROUND

The 5th-generation mobile communication technology (5th-Generation, 5G) New Radio (NR) is a newly proposed issue in 3rd Generation Partnership Project (3GPP) organization. As a discussion on the new generation of 5G technology gradually deepens, on the one hand, since a communication system is backward compatible, a new technology developed later tends to be compatible with a previously standardized technology; on the other hand, since there are already a large number of existing designs in the 4th Generation mobile communication (4G) Long Term Evolution (LTE), in order to achieve compatibility, it will inevitably sacrifice a lot of flexibility of 5G, thereby reducing the performance. Therefore, there are currently two parallel research directions in the 3GPP organization, where a technical discussion group that does not consider backward compatibility is referred to as the 5G NR.

In a LTE system, a Transport Block (TB) refers to a data block including a Media Access Control (MAC) Protocol Data Unit (PDU), and this data block will be transmitted on a Transmission Time Interval (TTI), and is also a unit for data retransmission in a Hybrid Automatic Repeat Request (HARD). In the LTE system, New Data Indication (NDI) signaling in a downlink control signaling is used to indicate whether a currently scheduled transport block is new data. If the currently scheduled transport block is new data, a value in a NDI information domain is inverted. That is, when a value of a NDI corresponding to a latest scheduled transport block before the currently scheduled transport block is 1, the NDI is inverted to 0 if the current schedule is new data, and the NDI is still 1 if it is retransmitted data. Since the NDI adopts an inverting setting method, a terminal can only determine that the currently scheduled transport block is new data compared to a last scheduled transport block, and cannot accurately know whether the currently received transport block is transmitted for the first time.

Currently in the 5G NR system, it is determined to support coding block group based feedback and retransmission for improving transmission efficiency, where one coding block group includes at least one coding block, and one transport block includes at least one coding block group. A sending end only needs to retransmit a coding block in a coding block group that fails to be decoded, and does not need to retransmit the entire transport block, and a base station can dynamically indicate a number of coding block groups included in one transport block through a downlink control signaling, and it is a problem of how to dynamically indicating the coding block group in the downlink control signaling that needs to be solved.

DESCRIPTION OF EMBODIMENTS

Technical solutions in the embodiments of the present disclosure will be described below with reference to the accompanying drawings.

Referring to FIG. 1, FIG. 1 is a possible network architecture of an example communication system according to an embodiment of the present disclosure. The example communication system may be, for example, a Global System for Mobile communications (GSM), a Code Division Multiple Access (CDMA) system, a Time Division Multiple Access (TDMA) system, Wideband Code Division Multiple Access (WCDMA) system, Frequency Division Multiple Access (FDMA) system, Orthogonal Frequency-Division Multiple Access (OFDMA) system, single carrier FDMA (SC-FDMA) system, General Packet Radio Service (GPRS) system, LTE system, 5G NR system and other such kind of communication systems.

When the communication connection mode is the single-connection mode, the network-side device may be an LTE base station or an NR base station (also referred to as a gNB base station), when the communication connection mode is the dual-connection mode (specifically, it can be implemented by carrier aggregation (CA) technology, or implemented by multiple network side devices), and the terminal is connected to multiple network side devices, the multiple network side devices may be a primary base station master cell group (MCG) and a secondary base station secondary cell group (SCG), and the base stations perform data backhaul through a backhaul link, the primary base station may be an LTE base station, and the secondary base station may be an LTE base station, or the primary base station may be an NR base station, and the secondary base station may be an LTE base station, or the primary base station may be an NR base station, and the secondary base station may be an NR base station.

In the embodiments of the present disclosure, the terms “network” and “system” are often used interchangeably, and those skilled in the art can understand the meaning thereof. The terminal involved in the embodiments of the present disclosure may include various handheld devices, in-vehicle devices, wearable devices, computing devices, or other processing devices connected to a wireless modem, all of which has a wireless communication function, and User Equipment (UE), Mobile Station (MS), terminal device of various forms, and the like. For convenience of description, the devices mentioned above are collectively referred to as a terminal.

Referring to FIG. 2A, FIG. 2A is a data indicating method according to an embodiment of the present disclosure, the method includes:

in part 2 a 01, a network side device sends a downlink control signaling to a terminal.

in part 2 a 02, the terminal receives the downlink control signaling from the network side device, where the downlink control signaling includes a first information domain and a second information domain, the first information domain is configured to indicate whether a transport block scheduled by the downlink control signaling is a new transport block, and the second information domain is configured to indicate a coding block group scheduled by the downlink control signaling.

The first information domain and the second information domain are further configured to indicate a number of coding block groups included in the new transport block.

The new transport block specifically includes the following two cases:

1. the new transport block is a transport block sent by the base station for the first time; and

2. the new transport block is different from a previous transport block of the new transport block.

The new transport block being different from the previous transport block of the new transport block is specifically that data information included in the new transport block is different from data information included in the previous transport block.

The second information domain being configured to indicate the coding block group scheduled by the downlink control signaling specifically includes the following two cases:

1. the second information domain is configured to indicate the number of the coding block groups scheduled by the downlink control signaling;

2. the second information domain is configured to indicate whether a scheduling resource corresponding to the downlink control signaling carries the coding block group.

The transport block scheduled by the downlink control signaling includes at least one coding block group, and the coding block group includes at least one coding block. A division strategy of the coding block group in the transport block may be a random division strategy, a data volume equalization division strategy, or a division policy based on a specific service requirement, etc., and the division strategy of the coding block group in a preset transport block is not limited in the embodiments of the present disclosure.

In part 2 a 03, the terminal determines a number of coding block groups included in the new transport block according to the first information domain and the second information domain.

It can be seen that, in the embodiments of the present disclosure, the terminal first receives the downlink control signaling from the network side device, where the downlink control signaling includes the first information domain and the second information domain, the first information domain is configured to indicate whether the transport block scheduled by the downlink control signaling is a new transport block, and the second information domain is configured to indicate the coding block group scheduled by the downlink control signaling; and then, determines the number of the coding block groups included in the new transport block according to the first information domain and the second information domain. It can be seen that, the number of the coding block groups in the scheduled new transport block can be determined according to the first information domain and the second information domain in the downlink control signaling, and the terminal device is enabled to achieve determination of a number of bits of an uplink control signaling that is fed back based on the number of the coding block groups, which is beneficial to reduce an uplink control signaling overhead.

In a possible example, the second information domain indicates the coding block group scheduled by the downlink control signaling in a Bitmap manner.

A bit length of the second information domain is agreed by a protocol or configured by a network device.

In a possible example, the terminal determines the number of the coding block groups included in the new transport block according to the first information domain and the second information domain, includes:

the terminal determines that the transport block scheduled by the downlink control signaling is a new transport block according to the first information domain;

the terminal determines that values of first K bits in the second information domain are all a preset value or values of last K bits in the second information domain are all the preset value, where K is a positive integer;

the terminal determines that the number of the coding block groups included in the new transport block is K.

The preset value may be 1 or 0. When the values of the first K bits in the second information domain are all 1 or 0 or the values of the last K bits in the second information domain are all 1 or 0, the number of the coding block groups included in the new transport block is K.

For example, the preset value is 1, when the second information domain is {1,1,1,0}, it indicates that there are three coding block groups in the new transport block, where a value of 1 indicates that the scheduling resource contains a coding block group to be transmitted, and a value of 0 indicates that the scheduling resource has no coding block group to be transmitted.

It can be seen that, in this example, the terminal determines the number of the coding block groups according to the preset value in the second information domain, which is beneficial to improve a convenience of determining the number of the bits of the uplink control signaling that is fed back.

In this possible example, after the terminal determines the number of the coding block groups included in the new transport block according to the first information domain and the second information domain, the method further includes:

the terminal sends acknowledgment (ACK) or non-acknowledgment (NACK) information for K bits of the new transport block to the network side device.

It can be seen that, in this example, when determining the number of the coding block groups included in the new transport block, the terminal sends acknowledgement/non-acknowledgement (ACK/NACK) information for the K bits of the transport block to the network side device, which is beneficial for the network side device to determine whether a transmission of the transport block is completed or whether a retransmission is needed, which is beneficial to improve an integrity of a mobile communication system.

In a possible example, the first information domain is a New Data Indication (NDI) information domain.

A specific implementation manner for the terminal to determine that the transport block scheduled by the downlink control signaling is a new transport block according to the first information domain may be that:

when a value of the first information domain is 1 and a value of a first information domain in a downlink control signaling scheduling a previous transport block of the transport block is 0, the terminal determines that the transport block scheduled by the downlink control signaling is a new transport block;

when the value of the first information domain is 0 and the value of the first information domain in the downlink control signaling scheduling the previous transport block of the transport block is 1, the terminal determines that the transport block scheduled by the downlink control signaling is a new transport block.

In a possible example, the method further includes:

the terminal determines that the transport block scheduled by the downlink control signaling is a new transport block according to the first information domain;

the terminal determines that values of first K bits in the second information domain are not all a preset value or values of last K bits in the second information domain are not all the preset value; and

the terminal does not send ACK/NACK information for the new transport block to the network side device.

For example, the preset value is 1, and when the second information domain is {0,1,0}, the values of the first K bits are not all 1 or the values of the last K bits is not all 1, the terminal does not send the ACK/NACK information for the new transport block to the network side device.

Consistent with the embodiment in FIG. 2A, referring to FIG. 2B, FIG. 2B is another data indicating method according to an embodiment of the present disclosure, the method includes:

in part 2 b 01, the network side device sends a downlink control signaling to a terminal;

in part 2 b 02, the terminal receives the downlink control signaling from the network side device, where the downlink control signaling includes a first information domain and a second information domain;

in part 2 b 03, the terminal determines that the transport block of the downlink control signaling is a new transport block according to the first information domain;

in part 2 b 04, the terminal determines that values of first K bits in the second information domain are all a preset value or values of last K bits in the second information domain are all the preset value, where K is a positive integer;

in part 2 b 05, the terminal determines that a number of a coding block groups included in the new transport block is K;

in part 2 b 06, the terminal sends ACK or NACK information for K bits of the new transport block to the network side device;

in part 2 b 07, the network side device receives the ACK/NACK information for the K bits of the new transport block from the terminal.

It can be seen that, in the embodiments of the present disclosure, the terminal first receives the downlink control signaling from the network side device, where the downlink control signaling includes the first information domain and the second information domain, the first information domain is configured to indicate whether the transport block scheduled by the downlink control signaling is a new transport block, and the second information domain is configured to indicate the coding block group scheduled by the downlink control signaling; and then, determines the number of the coding block groups included in the new transport block according to the first information domain and the second information domain. It can be seen that, the number of the coding block groups in the scheduled new transport block can be determined according to the first information domain and the second information domain in the downlink control signaling, and the terminal device is enabled to achieve determination of a number of bits of an uplink control signaling that is fed back based on the number of the coding block groups, which is beneficial to reduce an uplink control signaling overhead.

The terminal, when detecting that a value of a NDI of a first information domain in a downlink control signaling that schedules a previous transport block of the transport block is 0, determines that the transport block is a new transport block, and then, determines a coding block group included in the new transport block according to the second information domain:

when the second information domain is {1,1,1,1}, it indicates that the new transport block includes 4 coding block groups;

when the second information domain is {1,1,1,0} or {0,1,1,1}, it indicates that the new transport block includes three coding block groups;

when the second information domain is {1,1,0,0} or {0,0,1,1}, it indicates that the new transport block includes two coding block groups; and
